POST /tools/tx_simulator
SolAgent · tx_simulator — Simulate a base64-encoded Solana transaction without broadcasting it. Returns success/err, decoded failure reason, programs touched, writable accounts, compute units consumed, priority-fee estimate (SOL+USD), and a category (would-swap / would-transfer / would-fail). Drop-in for OATP's tx_simulator, priced 1c cheaper. Solana mainnet, settled in USDC.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
